摘要 目的观察心电图(ECG)检查在急性心肌梗死(AMI)靶血管定位中的应用。方法将经明确诊断为AMI的274例患者按ECG的ST段抬高与否分为急性ST段抬高心肌梗死(STEMI)186例与急性非ST段抬高心肌梗死(NSTEMI)88例,计数两组病例中ECG与冠脉造影(CAG)阳性病例数,比较ECG定位与CAG检查结果,比较两组CAG结果,并进行统计学分析。结果 274例患者中,CAG阳性者267例,其中ECG有改变者245例,CAG阴性者7例,其中ECG有改变者5例。ECG诊断AMI的检出阳性率为89.4%,敏感性为90.3%,特异性为42.9%。ECG定位梗死部位为广泛前壁39例,经CAG检查病变部位为左前降支(LAD)6例、右冠脉(RCA)+LAD 5例、LAD+左回旋支(LCX)13例、RCA+LCX 2例、多支病变13例;ECG定位梗死部位为正前壁46例,经CAG检查病变部位为LAD 12例、RCA+LAD 1例、LAD+LCX 13例、多支病变20例;ECG定位梗死部位为前侧壁34例,经CAG检查病变部位为RCA 2例、LAD 14例、LCX 3例、RCA+LAD 2例、LAD+LCX 5例、多支病变8例;ECG定位梗死部位为前间壁13例,经CAG检查正常2例、病变部位为LAD 2例、LCX2例、RCA+LAD 2例、LAD+LCX 1例、多支病变4例;ECG定位梗死部位为下壁51例,经CAG检查正常2例、病变部位为RCA 16例、LCX 6例、RCA+LAD 7例、RCA+LCX 4例、多支病变16例;ECG定位梗死部位为下侧壁45例,经CAG检查病变部位为RCA 6例、LCX 9例、RCA+LAD 6例、RCA+LCX 6例、多支病变18例。与NSTEMI组比较,STEMI组单支病变比例高(P<0.05),侧支循环及慢性钙化闭塞性病变比例低(P<0.01)。结论 ECG对于AMI靶血管的判断具有较好的提示作用,可用于初步判断AMI病变的靶血管。
